Getting ready to put the donor motor into my car and I lost track of where the vacuum lines go. Back of the motor below the intake manifold (bolted to the block). Has a pair of vacuum lines from sensor/solenoid?- one goes to maybe the throttle body. Other goes to what? Uploaded pics to IMGUR cause I'm not that smooth with the forums yet.

I searched through electrical diagrams and keep searching diff sensors online but not seeing the right one. Not finding a clear enough picture of the vacuum diagrams to wrap my head around.

Any help appreciated.

Might have bit off a little more than I could chew with this project. Also:

looped power steering lines/removed pump/pulley
removed heater core
removed coolant bottle
removed idler pulley for new belt routing. Used 52.25" belt but prob should change to a 53" as the 52 and 1/4" was a bear to get on

I got the car to run with perrys help but when i got a timing light on it its 180 approx from TDC. Current trigger tooth #1 angle BTDC is 90. I tried 180 and it wont start. Is there a setting i may need to play with? Btw using Audi COP setup and the timing light gripper is around the pigtail for #1.

In gen3 S2s the P0410 code is often caused by hardening and breakage of the emission tubing that runs across the passenger side of the valve cover.
Here are measurements for the tubing and connectors. If you leave it disconnected, your engine will idle high and burn extra fuel.

The connectors are NOT available at either Autozone or O'reillys. If anyone knows where to get the rubber bits, that might be helpful.

The connectors:
Back of the engine, straight connector:
Big end ID: 3/8
Little end ID: 5/32

Front of engine elbow connector:
Big end ID: 3/16"
Little end ID: 5/32"

Synopsis:

2001 Sc2A

Been sitting for 2 months with no attempt to start

Previously started right up

Just replaced valve cover gasket and replaced spark plugs thinking that gasket failure and fouled plugs were the cause of the no-start.

Fresh plugs and gasket and sopped up any excess oil on top the pistons.
Fuel pressure is present at the schraeder valve.
Battery is good.
Starter motor is good, or seems to be.

Turn the key and it cranks, ignition begins, and then fails. I can hear the initial FOOM in the cylinder, but that's it.

Gonna try starter fluid just to see if I can get it to go at all.

There must be some underlying problem that I missed.

Any ideas?

Mon, 04 Feb 2019 20:39:44 GMTIt's raining and one of my SC2s has sprung a leak.

2001 SC2 automatic. The front is up on ramps, so the car is at an angle.

Water was pooling behind on the rear floor passenger side.

I put a towel there to absorb it as it comes ins. Now I find water pooling UNDER the carpet. I can push down on the carpet and watch the waves beneath it.

It does not appear to be coming through the door.

How else might it be getting in?

My assumption was that the rocker cover gasket was not sealing around the plugs, and this proved to be correct.

This is my first time having a valve cover off of a car. (motorcycles, sure, cars no)

I'd like to only have to install it once. So I have some basic questions:

When I pulled the rocker cover off here is what I found:

The gasket appeared to be good. (replacing anyway)

The fasteners were unevenly torqued. Some required a little elbow and others required no elbow to loosen.

There was RTV gasket maker on only the short side near the timing chain.

I have seen a different SC2 which had a massive oil leak at the timing chain end of the rocker cover.

Questions:

Is there a design flaw that necessitates RTV at that location, or is what I'm seeing likely a case of sloppy installation?

Is there anything peculiar to this engine that's going to come back and bite me in the rear 200 miles from now?

Are there any other possibilities beside the gasket that could cause the spark plugs to be fouled with fresh oil?

Here's a picture of the engine top. You can see where the spark plug gasket had oil flowing around it.

Thu, 31 Jan 2019 05:14:46 GMTI'm preparing to rebuild my oil burning gen3 SC2 and would like to know which pistons I should get to solve the oil burning problem.

I've used the HF compressor tool with success until I ended up jacking up a piston one fateful night putting together the engine for the offroad build.
After that I ordered two taper compressors for 82 and 84mm, both which work great.
I could order another taper deal, but wanted to gauge the room to see who has used the plier type compressors before. Will these be the same headache that the HF deal is?

I'll probably end up reusing the old one with some red threadlocker.

Has anyone found a suitable replacement for it?
